Hello everyone
Merry Christmas
I need an advice I have the following code:
int main()
{
int k=5000000;
int p;
int sum=0;
for (p=0;p<k;p++)
{
sum+=p;
}
return 0;
}
When I assemble it I get
main:
pushl %ebp
movl %esp, %ebp
subl $16, %esp
movl $5000000, -4(%ebp)
movl $0, -12(%ebp)
movl $0, -8(%ebp)
jmp .L2
.L3:
movl -8(%ebp), %eax
addl %eax, -12(%ebp)
addl $1, -8(%ebp)
.L2:
movl -8(%ebp), %eax
cmpl -4(%ebp), %eax
jl .L3
movl $0, %eax
leave
ret
If I run it through gprof I get that main executed the most, which is quite obvious!
Yet I want to go a step further and be able to know if L2, or L3 executed the most. here it is obvious that L3 executed the most. yet is there some kind of profiler, emulator that can give me that data for an entire code?
